Our valve covers are designed & machined in the USA.  We take pride in our work & these high-quality covers are a great addition to your current build. 

Our valve covers are CNC machined from 6061-t6 aluminum. Drilled and threaded to accept standard 1/8" brass fittings that you will find in any hardware store. 1.3" of clearance will clear oversized roller rockers but also works great on stock motors.
